Abstract:
The electric response signal of dark adapted bacteriorhodopsin excited by a laser flash was studied. By a subtraction method the electric signal corresponding to the bacteriorhodopsin containing 13-cis retinal could be separated. This electric signal contains three components, corresponding to three steps in the charge movement induced by the laser flash. The lifetimes of these steps are correlated with the photocycle of the bacteriorhodopsin containing 13-cis retinal.
